What CERN scientists are claiming from one of their most recent is that the universe itself is nothing short of a miracle, because it really shouldn’t even exist. This claim is based on the Big Bang theory. Even though this theory is the most prevailing, it is not the lone theory that explains how all things came into existence. This view begins with the singularity.
Problems with the Big Bang theory
As believes by Big Bang believers, our universe existed once as a single point that was no bigger than a grain of sand. This point was incredibly hot, unimaginably dense, and was literally packed with energy and matter. And then the single little point exploded, spewing its contents outward and eventually, the universe was formed. There are a couple of problems with the Big Bang theory. For starters, there is the fact that the rate of universal expansion is increasing – this is known as the Hubble Constant. According to the theory, universal expansion ought to be getting slower or even pulling back. Dark matter and dark energy is the most common explanation, but we are unable to prove its existence.
Dealing with Matter and Antimatter
But there is another issue and this is where the scientists from CERN come in. The environment that is responsible for producing all particles that exist in the universe should have produced the same quantity of matter and antimatter. The problem is that antimatter is remarkably rare.
One reason is that antimatter and matter must somehow be extremely different. But this recent CERN experiment does not support this notion. If we refer to the Standard Model of physics, which is a manual about every particle that is known in our universe and how it functions, every kind of atom has its very own polar opposite which is called its antiparticle, and it has the very same mass but with the exact opposite electric charge.
During this particular study, CERN scientists were attempting to determine the fundamental differences that these particles must have in order to validate the universe’s existence. And they came up totally empty. Physicists at CERN had evaluated the magnetic characteristics of protons and antiprotons with amazing precision. The good news was that these new findings totally supported the Standard Model, since the behavior of the particles was as predicted.
This matter-antimatter imbalance, as it is called today, has become a topic of conversation between particle physicists recently, and there are several research teams addressing this issue worldwide. CERN researcher Christian Smorra was one of the team members who participated in this recent experiment. He said recently, “All of our observations find a complete symmetry between matter and antimatter, which is why the Universe should not actually exist.”
He also pointed out, “An asymmetry must exist here somewhere but we simply do not understand where the difference is. What is the source of the symmetry break?” He and his team’s findings were posted in the publication Nature.
Antiprotons and protons were actually the very last holdout as far as particles which might shed light on this imbalance with matter-antimatter. Scientists who came from Mainz University located in Germany had come up with a method to evaluate the magnetism of antimatter which is around 350 times more precise than any previous method. In fact, this was measured to an amazing nine places!
And the measurement was an incredible -2.7928473441 nuclear magnetons. A proton has the exact same amount of magnetism, except that it is a positive number. Even though the study did not explain the universe’s prejudice toward matter, it provided much clearer understanding of the magnetism of an antiproton.
And the fast is that antimatter does not last very long. And because of this fact, it must be contained. Scientists actually used 2 Penning traps, which happen to be devices that are capable of retaining antimatter particles through the use of a magnetic field and an electrical field. Stefan Ulmer, who is the spokesperson representing the BASE collaboration at CERN, submitted the following press release:
“The measurement of antiprotons was extremely difficult, and we had been working on it for ten years. The final breakthrough came with the revolutionary idea of performing the measurement with two particles. This result is the culmination of many years of continuous research and development, and the successful completion of one of the most difficult measurements ever performed in a Penning trap instrument.”
Previously, scientists have sought out the differences among particles along with their opposites by measuring and comparing their respective electrical charges, magnetism levels, and their masses. Now they are interested in evaluating them in terms of gravity, to ascertain whether a disparity exists there. There is another international collaboration from CERN which is called ALPHA. This team intends to study whether or not there is any asymmetry that is present between antihydrogen and hydrogen atoms. And the BASE team is also planning to further evaluate antiparticles magnetically.
And there is yet an additional development at CERN, as a brand new linear accelerator will introduced soon at the facility. This will let the Large Hadron Collider (LHC) reach even greater luminosities by the year 2021. The director at CERN Fabiola Gianotti, spoke at its unveiling, “This high-luminosity phase will considerably increase the potential of the LHC experiments for discovering new physics and measuring the properties of the Higgs particle in more detail.” Perhaps some new discoveries here will lead to the unraveling of the matter-antimatter imbalance secret.
